SepGen: Multi-Stem Audio-Video Separation and Generation in a Single Model

Read the original on arXiv Computer Vision →

SepGen is a single model that extends a pretrained audio‑video generator to produce a video, its mixed soundtrack, and individual waveforms for each captioned sound source in one sampling run. It offers two modes: generation, where captions dictate the content of each stem (e.g., separate stems for each speaker in a dialogue), and separation, where the model extracts specified sources from a clean audio mix based on free‑text descriptions. The authors evaluate SepGen on text‑generated scenes, scenes rendered by other generators, and real recordings of speech, music, and sound effects, showing it outperforms language‑conditioned separators, especially on speech tasks.

Vorch-Omni: Multi-Task Orchestration of Sight and Sound

Recent advances in generative video modeling have enabled diverse generation, reference-based synthesis, extension, and editing, but existing approaches often rely on fragmented task-specific models. A general model must distinguish heterogeneous target, source, and reference signals to determine what to generate, preserve, or use as guidance, while reducing interference among tasks.

Vorch-Human: Unified Multi-Task Human-Centric Generation via Long-Horizon Continuation

Vorch-Human is a unified framework for human‑centric audio‑visual generation that handles multiple tasks—animating a person from speech, jointly generating speech and video from a voice reference, and synthesizing a scene from paired appearance and voice references—using a single dual‑stream audio‑video diffusion transformer. The model incorporates clean condition‑audio and condition‑video tokens, per‑token task embeddings, temporal position types, condition masks, and a shared multimodal prompt encoder to express diverse inputs such as driving speech, timbre examples, first frames, and subject images. A two‑level data pipeline supplies the necessary supervision by extracting speech, appearance, and timbre annotations from clips and linking consistent identity and outfit references across videos, while a frozen‑prefix recurrence enables long‑form audio‑driven generation with reduced boundary discontinuity and identity drift.
